I have a 6 volt motor scooter with a magneto/points ignition. I would like to extend the life of the points by using a 6 volt DC milliamp signal to control the unregulated AC output from the magneto coil. Is there a transistor that has an isolated input and output that can be used in the circuit? Maximum frequency of 1000Hz.

I looked at soild state relays but don't fully understand the spec sheets.

The owners of All About Circuits has elected not to host discussions of automotive electrical system modifications/enhancements due to safety concerns, the potential of legal ramifications and the possible circumvention of vehicle regulations at the state and federal level.
